Hi Everyone, I’m starting to learning unreal engine by the tutorial by unreal sensei but after I focus on the material and make a wooden box I notice that my box color look different from the tutorial so I’m trying too set color tint but in the tutorial set it to rgba(1,1,1,1) so I do the same to on-ground material but even It all is the same but my ground and box material still look different from the tutorial and it looks to have some white tone in it, look too bright and even I’m setting my exposure to the game setting mode it’s still look white. Please help me I’m really stuck at this point and cannot continue the tutorials
